There were no significant differences between the percentage of follicular CD8 cells that expressed either GRα or GRβ between COPD patients (means 50.9% and 30.4% respectively) and controls (mean 52.9% and 29.7% respectively), p = 0.8 and 0.9 respectively; see Figure 3 for individual data and representative images. This evidence concerns the gene CD8A and chronic obstructive pulmonary disease.
